MOP WRINGER Filed Jan. 14, 1936 Patented Apr. 13, 1937 avast 2 Claims.

This invention relates to mop-wringers, and is especially adapted forum in co-operation with removable pails or like receptacles, and one of the principal objects is the production of a wringer which may be used in connection with any preferred form of pail or receptacle.

A further object of this invention is the procluction of a novel mop-wringer which is not only convenient to use, but is easy to operate through 1 the medium of foot or hand power, is light in weight, simple, sturdy, inexpensive and efiicient in operation, for the purpose of pressing water from a mop, sponge, or cloth, and the like, when any article of this character is immersed in water contained in the receptacle, and then wrung by passing between the compressed wringer rolls.

Another object of this invention is the production of a simple and eflicient means for limiting the swinging movement of the movable roller member to an open position.

A still further object of this invention is the production of a mop-wringer, the moving parts of which produce a multiple leverage between the movable treadle and the movable roller supporting member whereby the pressure may be increased upon the wringer rollers as the treadle member is forced downwardly with a minimum amount of effort.

Other objects and advantages of the present invention will appear throughout the following specification and claims.

In the drawing:

Figure 1 is a side elevation of the mop-wringer;

Figure 2 is a top plan View thereof;

Figure 3 is a front elevation of the upper end of the pivoted roller housing member;

Figure 4 is a side elevation of the mo in a folded position;

Figure 5 is a transverse sectional view taken on line 5-5 of Figure 1; and

Figure 6 is a transverse sectional view taken on line 6-6 of Figure 5.

By referring to the drawing, it will be seen that I I] designates the base frame which carries transversely extending pail-supporting straps l l which are arranged in spaced relation and are provided with upstanding ears i2, the ears l 2 being riveted or otherwise secured to the base frame H], as shown in Figure 1. A pair of base brackets l3 are carried by the frame iii, as shown in Figure 2, these brackets being preferably riveted to the inner sides of the frame ii These base brackets it support a substantially inverted U-shaped rigid roller housing member M, which member 55 I4 extends vertically, and is located in approxip-wringer mately the center of the frame it]. The rigid roller housing member M is provided with an inset frame l5 at its upper end in which is mounted a roller Hi and a handle it is mounted upon the upper end of the inset frame i5, as shown in Figure 3. The rollers l6 and 23 may be provided with journal extensions I8 for receiving a crank I9 to allow the rollers I 6 and 23 to be manually rotated, if desired, through the medium of the crank iii.

A movable roller housing member 26 is pivotally secured, as at 2!, to the base frame It), and this member 20 is a substantially U-shaped member, as shown in Figure 2. The movable member 2|] is provided with an inset frame 22 in which is rotatably mounted a roller 23. The rollers i6 and 23 are mounted upon their respective members l4 and 28 so as to project inwardly beyond the inner or adjacent faces of the respective framesnote particularly Figure 1. The frame ii! is preferably provided with an inwardly bent lug 24 upon each side thereof formed by cutting and bending the side rails of the frame, these lugs 24 providing a stop and rest to limit the swinging of the movable member iii to an open position.

A treadle yoke 25 is pivoted at its inner ends, as at 26, to the base brackets l3 upon either side of the frame EB, and this treadle yoke 25 preferably tapers toward its forward end, as at 2'!- note particularly Figure 2. An angle foot plate 28 is'carried by the outer end of the treadle yoke 25 and is mounted to overhang the front and topedge of the treadle yoke 25, as shown in Figures 1 and 2.

The movable member 26) and the treadle yoke 25 are connected near their lower ends by means of the pivotally connected links 29 and 39, the links 29 and 30 being pivotally connected by a free pivot, as at 36, and a set of these links being secured to each side of the yoke and movable member above mentioned. The links 29 upon each side of the mop-wringer are pivoted as at 32, to the movable member 26, and the links 3! are pivotally connected, as at 33, upon each side of the treadle yoke 25. When the mop-wringer is in its completely open position, the pivots 32 and 33 are in substantially horizontal alignment with the pivot connection 3!. As the treadle yoke 25 is forced downwardly, however, the alignment of the pivots 3!, 32 and 33, will constantly change, or will simultaneously change due to the downward movement of the treadle and the closing movement of the roller housing member 20. Consequently, as the treadle member 25 is forced to its downward position or a near horizontal position at the end of its downward movement, a greater leverage will be exerted but at the same time requiring less foot pressure to produce the desired power developed for wringing a mop which may be placed between the rollers l6 and 23.

Attention is now invited to Figure 4 and it will be noted that because of the links 29 and 30, the treadle yoke 25 may be swung to a vertical position so that the same may extend substantially parallel to the upright or vertically extending rigid roller housing member I 4, the links 29 and 30 folding upwardly, as shown in Figure 4, at the same time moving the movable member 28 to a substantially parallel position with respect to the member M. This folded position is especially adapted for packing and shipping and will cause the device to be accommodated in a minimum amount of space while being packed and shipped.

As shown in Figure 1, a pail P is indicated in dotted lines, and this pail may be of any character or type and may be placed upon the pail supporting straps ll under the rollers l6 and 23 carried by the members I 4 and 20. The mop or other similar article may be then drawn up between the rollers I6 and 23, as the treadle yoke 25 is depressed for the purpose of wringing the mop or other device. Through the medium of the crank I9, either the roller 23 or IE may be manually rotated, if desired.

Having described the invention, what I claim as new is:--

1. A mop-wringer comprising a base, a rigid roller housing member carried by said base and extending above the same, a wringer roller carried by the wringer roller housing member, a movable member pivotally secured to the base adjacent the roller housing and carrying a roller adapted to coact with said first mentioned roller, a treadle yoke pivotally supported in conjunction with the base adjacent to said roller housing and capable of being swung to a substantially parallel position with respect to the rigid member, a link pivotally connected to said movable member, a second link pivotally connected to said treadle yoke, a free pivot connecting the links whereby the links may be folded to permit the treadle yoke and movable member to extend in substantially parallel relation to said rigid roller housing member, the links lying in substantially the same plane when the treadle member and movable member are in an open position, the movement of the treadle yoke to a depressed position automatically changing the pivot points of connection with the movable member and the treadle member to change alignment to increase the leverage and reduce the efiort necessary to move the movable member from an inoperative to an operative position.

2. A mop-wringer of the class described comprising a base frame, a substantially centrally located roller supporting member fixed against movement with respect to the base in a position to overhang a pail adapted to be supported upon said base, a movable roller supporting member pivotally mounted upon the base, base brackets carried by the base and engaging the centrally located roller supporting member, a treadle yoke pivotally secured to said base brackets, a link connected to the movable roller supporting member, a link connected to said treadle yoke and a free pivot connecting said links whereby said movable roller supporting member may be swung to a wringing position with respect to the centrally located roller supporting member as the treadle yoke is depressed and also whereby said links may be folded.
